Hi Haolun,
You cannot update the records from a report.
A simple alternative to updating the records from within salesforce is using the enhanced list views.
Create a List view on Contact object and Filter the List view using the same criteria that you used in the report and you can then mass edit the records fdirectly from a List view.
In order to mass update the records from the list view you need , inline editing and enhanced lists enabled for your organization
Editing Records Directly From Enhanced Lists
